Effect of CYP2D6 Poor Metabolizer Phenotype on Stereoselective Nebivolol Pharmacokinetics

Conclusion: The decline in plasma concentration of both nebivolol isomers in PM phenotypes, especially those with MR of 220 and 244, which indicate minimal or absent CYP2D6 activity, points to alternative mechanisms for nebivolol elimination. Collectively, our results are the first to show the significant impact of CYP2D6 PM phenotype on the metabolic disposition and in vivo exposure to both nebivolol isomers.
